How is the thrust related to pressure?

उत्तर
Pressure is directly proportional to thrust P µ Thrust
i.e. greater the thrust, greater is the pressure and smaller the thrust, smaller is the pressure.
Force simply refers to push or pull on an object, whereas thrust refers to the reaction force acting on an accelerated object due to the force which is applied to that object. Therefore, the relationship between thrust and pressure is that pressure is directly proportional to thrust.
